[0053] Reference Figure 1 As shown, a cover assembly 1000 according to an embodiment of the present invention can be installed on the housing of a water heater 2000, thereby facilitating the installation of a structure such as an electric control device. Figure 2 and Figure 3 As shown, the cover assembly 1000 includes a first cover 100 and a second cover 300. The first cover 100 is provided with positioning holes 110 and a first clamping structure 200 at intervals. The positioning hole 110 is located at one end of the first cover 100 along a first direction. For example, the first direction may be an up-down direction, and the positioning hole 110 may be located at the lower end of the first cover 100. The inner side wall of the first cover 100 is provided with a guide rib 111. For example, the first cover 100 is provided with a through hole 130, and the through hole 130 is in a long strip shape and extends in the up-down direction. The positioning hole 110 may be located at the lower end of the through hole 130, and the first clamping structure 200 is located at the side and upper end of the through hole 130. Referring to Figure 4 As shown, the second cover body 300 is provided with a positioning member 310 and a second clamping structure 400 . The positioning member 310 is located at the lower end of the inner side wall of the second cover body 300 , and the second clamping structure 400 is distributed along the circumference of the inner side wall of the second cover body 300 .

[0054] By adopting the above scheme, when assembling the first cover body 100 and the second cover body 300, the positioning piece 310 at one end of the second cover body 300 is inserted into the positioning hole 110 for pre-positioning, so that the first guide surface 311 of the positioning piece 310 and the guide rib 111 are guided and matched, thereby quickly determining the relative position of the first cover body 100 and the second cover body 300. Then the other end of the second cover body 300 is rotated in the direction close to the first cover body 100, so that the first clamping structure 200 and the second clamping structure 400 are clamped, thereby making the first cover body 100 and the second cover body 300 fixedly connected. By adopting this scheme, the relative position of the first cover body 100 and the second cover body 300 can be quickly determined by the method of pre-positioning and then clamping, the assembly process is simple and convenient, the assembly time can be shortened, and the assembly efficiency can be improved.

[0055] Reference Figure 5As shown, in the embodiment of the present invention, the positioning member 310 includes a positioning portion 312 and an elastic portion 313. One end of the positioning portion 312 is connected to the side of the second cover body 300 facing the first cover body 100, one end of the elastic portion 313 is connected to the other end of the positioning portion 312, and the other end of the elastic portion 313 is bent toward the guide rib 111. The elastic portion 313 is elastic, and a first guide surface 311 is provided on the side of the elastic portion 313 facing the guide rib 111. In the direction away from the positioning portion 312, the distance between the first guide surface 311 and the second cover body 300 gradually increases. Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, when the positioning member 310 is set in the positioning hole 110, during the rotation of the second cover 300, as shown in FIG. Figure 12 to Figure 11 In the order of, since the elastic part 313 is elastic and the distance between the first guide surface 311 and the second cover body 300 gradually increases, during the abutment and matching process between the first guide surface 311 and the guide rib 111, the positioning member 310 and the guide rib 111 are gradually clamped, and finally the positioning part 312 and the inner side wall of the positioning hole 110 are abutted and positioned. The position of the second cover body 300 relative to the first cover body 100 can be quickly determined, and the assembly efficiency of the first cover body 100 and the second cover body 300 is improved.

[0056] Reference Fig.12 As shown, in the embodiment of the present invention, a second guide surface 112 is provided on one side of the guide rib 111 facing the first guide surface 311, and the second guide surface 112 is tilted downward and away from the inner side wall of the first cover body 100. In other words, along the direction away from the positioning portion 312, the distance between the second guide surface 112 and the inner side wall of the first cover body 100 gradually increases. Through the guiding cooperation of the first guide surface 311 and the second guide surface 112, the second cover body 300 can be gradually clamped with the first cover body 100 during the rotation process, and it is more stable, so as to quickly determine the relative position of the first cover body 100 and the second cover body 300. At the same time, the connection between the positioning member 310 and the positioning hole 110 is not in a stuck state, so it is convenient to disassemble the second cover body 300, which is conducive to maintenance, cleaning, etc.

[0057] Reference Figure 3As shown, in the embodiment of the present invention, the positioning hole 110 includes a first hole section 114 and a second hole section 115, the first hole section 114 and the second hole section 115 are connected, and the first hole section 114 is located above the second hole section 115. Among them, the width of the first hole section 114 gradually decreases in the direction close to the second hole section 115, while the width of the second hole section 115 can remain unchanged, and the width of the second hole section 115 is equal to the minimum width of the first hole section 114, so that the positioning hole 110 is in a bell-mouth shape. It should be noted that the width of the first hole section 114 and the width of the second hole section 115 refer to the width in the left and right direction. It can be understood that since the opening of the first hole section 114 is larger, the positioning member 310 can be firstly penetrated in the first hole section 114, and then moved in the direction close to the second hole section 115, which is convenient for the installation and positioning of the positioning member 310, so as to improve the assembly efficiency of the positioning member 310 and the positioning hole 110.

[0058] Reference Figure 3 As shown, in the embodiment of the present invention, the inner side wall of the second cover body 300 is provided with a first reinforcing rib 113, and the first reinforcing rib 113 is arranged around the positioning hole 110 to improve the overall strength of the positioning hole 110, and effectively avoid the positioning hole 110 from cracking, excessive deformation, etc. For example, the first reinforcing rib 113 can be arranged around the periphery of the first hole section 114 and the periphery of the left and right sides of the second hole section 115. The first reinforcing rib 113 is not arranged on the lower periphery of the second hole section 115, so as to avoid the first reinforcing rib 113 affecting the cooperation between the positioning member 310 and the guide rib 111.

[0059] Reference Figure 8 As shown, in the embodiment of the present invention, along the second direction perpendicular to the first direction, for example, the second direction is the left-right direction, two positioning members 310 and two positioning holes 110 are provided at intervals. A limiting surface 314 is provided on one side of one positioning member 310 facing the other positioning member 310, and the limiting surface 314 and the inner wall of the positioning hole 110 are abutted and limited, thereby limiting the displacement of the second cover body 300 along the left-right direction, so as to reduce the loosening and displacement of the second cover body 300, and at the same time, the relative position of the second cover body 300 and the first cover body 100 can be quickly determined, which is conducive to the first clamping structure 200 and the second clamping structure 400 clamping.

[0060] Reference Figure 4 and Figure 6As shown, the second clamping structure 400 includes a first clamping member 410, and the first clamping member 410 can be one or more. For example, there are four first clamping members 410, and the four first clamping members 410 are respectively arranged on the left and right sides of the second cover body 300, and two first clamping members 410 are arranged at intervals on one side, and the two opposite first clamping members 410 are symmetrically arranged on the second cover body 300 along the left and right directions. The first clamping member 410 includes a hook portion 411 and a protective portion 412. Along the direction from the second cover body 300 to the first cover body 100, the protective portion 412 is sequentially provided with a first positioning surface 4121 and an inclined fifth guide surface 4122. Figure 2 , Fig.15 and Fig.16 As shown, the first clamping structure 200 is provided with a first clamping hole 210, and the inner wall of the first clamping hole 210 is provided with a second positioning surface 212 and an inclined sixth guide surface 211 in sequence. When the first clamping member 410 is inserted into the first clamping hole 210, the fifth guide surface 4122 first cooperates with the sixth guide surface 211 to guide the direction of the first clamping member 410, and finally the hook 411 is clamped to the end wall of the first clamping hole 210, and the first positioning surface 4121 and the second positioning surface 212 are positioned and cooperated, so that the second cover body 300 and the first cover body 100 are clamped and fixed. Therefore, the clamping process of the first clamping member 410 and the first clamping hole 210 is simple and accurate, with good stability and not easy to loosen.

[0061] Reference Figure 6 As shown, in the embodiment of the present invention, two protective parts 412 are provided. In the up-down direction, the two protective parts 412 are respectively located at the two ends of the hook part 411 and are spaced apart from the hook part 411. The protective part 412 plays the role of protecting the hook part 411, effectively reducing the bending deformation, breakage, etc. of the hook part 411 caused by collision during transportation. The protective part 412 and the hook part 411 are spaced apart instead of being connected, so that the hook part 411 can have a certain elastic deformation ability, which facilitates the hook part 411 to be snapped with the end wall of the first snap-in hole 210. The protective part 412 also plays the role of guiding and positioning, so that the hook part 411 can be accurately snapped into the first snap-in hole 210.

[0062] Continue to refer to Figure 6 As shown, in an embodiment of the present invention, the first clamping member 410 includes a second reinforcing rib 413, which is connected to the hook portion 411 and the second cover body 300 to improve the overall strength of the hook portion 411, effectively reduce the risk of the hook portion 411 breaking, and improve the reliability of the first clamping member 410.

[0063] Due to the errors in the manufacturing and assembly process of the first cover 100 and the second cover 300, it is easy to cause the first clamping member 410 to be difficult to be accurately clamped to the first clamping hole 210. Fig.13 and Fig.14 As shown, in the embodiment of the present invention, the first clamping member 410 and the inner wall of the first clamping hole 210 are spaced apart in the up-down direction, that is, a design gap is reserved. When the first clamping member 410 changes position in the up-down direction due to an error, since the first clamping hole 210 has a design gap reserved, the first clamping member 410 can still be accurately clamped in the first clamping hole 210, effectively reducing the problem of the first clamping member 410 and the first clamping hole 210 not being able to be accurately installed due to an error.

[0064] Reference Fig.14 As shown, in the embodiment of the present invention, along the up-down direction, the maximum spacing between the first clamping member 410 and the inner wall of the first clamping hole 210 is L, which satisfies: 1mm≤L≤5mm. The minimum spacing between the first clamping member 410 and the inner wall of the first clamping hole 210 can be 0mm, that is, the first clamping member 410 and the inner wall of the first clamping hole 210 are in contact. It can be understood that, assuming L<1mm, the reserved design gap is too small and it is difficult to achieve the corresponding effect; when L>5mm, the strength of the first clamping hole 210 is reduced, which may lead to unstable clamping. Therefore, a reasonable design of the spacing between the first clamping member 410 and the inner wall of the first clamping hole 210 is conducive to the assembly of the first clamping member 410 and the first clamping hole 210, and improves the success rate.

[0065] Reference Figure 2 As shown, in the embodiment of the present invention, the first clamping structure 200 is provided with a second clamping hole 220, and the second clamping hole 220 is located above the through hole 130. Figure 4 As shown, the second clamping structure 400 also includes a second clamping member 420, which is located at one end of the second cover body 300 away from the positioning member 310, and the second clamping member 420 is clamped in the second clamping hole 220 to further limit the position of the second cover body 300 relative to the first cover body 100, thereby improving the stability of the connection between the second cover body 300 and the first cover body 100 and effectively reducing the loosening and falling off of the second cover body 300.

[0066] Reference Figure 2 As shown, in the embodiment of the present invention, two second engaging holes 220 are provided and are symmetrically arranged along the left and right directions. Figure 4 and Figure 7 As shown, there are two second clamping members 420, which are also symmetrically arranged along the second direction. A positioning rib 421 is provided on one side of the second clamping member 420 facing the other second clamping member 420. Fig.17 and Fig.18As shown, the positioning rib 421 is abutted against the inner wall of the second clamping hole 220 for positioning. Through the positioning cooperation between the positioning rib 421 and the inner wall of the second clamping hole 220, together with the positioning member 310 and the first clamping member 410, the displacement of the second cover 300 in the left-right direction can be limited, effectively preventing the second cover 300 from swinging in the left-right direction.

[0067] Reference Fig.18 As shown, in the embodiment of the present invention, an annular portion 221 is provided on the inner side of the first cover 100, a second clamping hole 220 is formed in the annular portion 221, and an inner wall of the annular portion 221 is provided with an inclined third guide surface 222, and a side of the positioning rib 421 facing the annular portion 221 is provided with an inclined fourth guide surface 422. In the process of inserting the second clamping member 420 into the second clamping hole 220, the third guide surface 222 and the fourth guide surface 422 are first in contact and then gradually clamped, thereby effectively limiting the displacement of the second cover 300 in the left-right direction.

[0068] Reference Figure 7 As shown, in the embodiment of the present invention, the structure of the second clamping member 420 is basically similar to that of the first clamping member 410, and also includes a hook portion, a protective portion, a second reinforcing rib and other structures, and the main difference is that the second clamping member 420 is further provided with a positioning rib 421 on the protective portion. The protective portion of the second clamping member 420 abuts against the lower wall surface of the second clamping hole 220, and the hook portion of the second clamping member 420 abuts against the upper wall surface of the second clamping hole 220, thereby limiting the displacement of the second cover 300 in the up and down direction.

[0069] A water heater 2000 according to an embodiment of the present invention may be an air energy water heater, and the water heater 2000 includes the cover assembly 1000 according to the above embodiment. The water heater 2000 according to the embodiment of the present invention adopts the cover assembly 1000 according to the above embodiment, and the cover assembly 1000 is provided with a positioning member 310 and a positioning hole 110. When assembling the first cover 100 and the second cover 300, the positioning member 310 at one end of the second cover 300 is inserted into the positioning hole 110 for pre-positioning, so that the first guide surface 311 of the positioning member 310 and the guide rib 111 are guided and matched, thereby quickly determining the relative position of the first cover 100 and the second cover 300. Then, the other end of the second cover 300 is rotated toward the direction close to the first cover 100, so that the first clamping structure 200 and the second clamping structure 400 are clamped, thereby making the first cover 100 and the second cover 300 fixedly connected. By adopting this solution, the relative positions of the first cover body 100 and the second cover body 300 can be quickly determined by pre-positioning and then snapping together. The assembly process is simple and convenient, which can shorten the assembly time and improve the assembly efficiency.
